To all whom it may concern:

Be it known that I, ZAGHARIAH H. DER- ;uirr'r, a citizen of the United States, residing at Buena Vista, county of Chaffee, and State of Colorado, have invented certain new and useful Improvements in Safety-Hatpins; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany ing drawings, and to the characters of reference marked thereon, which forma part of this specification.

` ll/Iy invention relates to an improvement in safety hat pins, my improved device including a specially formed body portion of a hat pin and a safety sheath or cover therefor, which is held in place with sufficient security to prevent its accidental removal, while at the same time `it may bev removed and applied as may be desired without difliculty.

'Ihe obj ect of my improvement is to provide a construction whereby the point of the hat pin is covered by a shield which prevents the pin point from coming in contact with parts of the bodies of people who may be in the vicinity of the wearer. It is well known that hat pins with exposed points have caused many serious accidents, some of which have resulted in blindness, while even more serious results have followed. Accidents of this character are quite frequent, and my object is, as above indicated, to provide a construction which will entirely overcome all diiiculties of this character.

lilly improvement consists of a hat pin whose body portion for a considerable distance from the point is roughened or corrugated in such a way as to be engaged by a locking member, as a spring, with which a sheath is equipped, the sheath having a central longitudinal perforation adapted to receive the pointed extremity of the pin, which when in place will be held against accidental removal, as above set forth. `The sheath or safety device applied to the pin point and a portion of the body of the pin adjacent thereto has a blunt rounded end of such character as to be absolutely harmless under conditions such as would produce serious accidents if the pin point were eX posed.

Having briefly outlined my improvement, I will proceed to describe the same in detail drawing in which is illustrated an embodiment thereof. In this drawing:

Figure 1 is an elevation of my improved safety hat pin.

Fig. 2 is a fragmentary sectional view of the same abnormally enlarged for the purpose of Iclearer illustration.

Fig. 3 is a fragmentary detail view of the specially constructed portion of the pin or that which is adapted to enter the sheath or cover. y

Fig. 4 is a horizontal section taken on the line l-4, Fig. 2.

The same reference characters indicate thel same parts in all the views.

Let the numeral 5 designate a hat pin having a portion 6 of the shank extending adj acent the point, corrugated or roughened, `whereby when a sheath 7 having a longitudinally disposed `central portion 8 is applied thereto, a spring 9 with which the sheath 'l is equipped at its outer extremity will engage depressions l() of the portion 6 of the pin. As shown in the drawing, the portion 6 of the pin is provided with circumferential recesses 10 which are spaced by slight enlargements 12. The spring 9 which is adapted to engage the recesses 10 as shown in the drawing, is of the leaf type and is secured, as,

shown at 13, in the mouth 14C of the liared extremity 15 of the sheath. This sheath as shown in the drawing is slightly smaller at its free extremity 16 than at any other part and gradually increases slightly in diameter toward the mouth 14C, where it is quite abruptly flared making it practicable to form the mouth or cavity 14 of such size as to guide the pin point when the sheath is applied to the pin. This feature is of considerable importance, since the sheath will always be applied'to the pin after the hat is in place upon the head, and consequently, under such circumstances that in many instances it would be necessary for the user to apply the device without an opportunity to observe its application. In any event the flaring open-mouthed portion of the sheath will facilitate the placing of the safety device in position upon the pin, whereas, if the mouth of the device had the same sized opening as is formed beyond the same, consider able difficulty might be experienced in applying the sheath, as will be readily understood.

It should be explained that the inner or lflll l curved outwardly `in order to fit approxi- `snpeath and the specially prepared part 6 of Vthe pin being such as to allow Afor a considmately the recesses 100i1 the portion 6 of the pin.l Y rlhe parts 12 between the recesses 10v are roundedor curved, whereby theengag- 'ing portion 17 of the spring will pass easily Vover them when the pin is moved in either direction. Still the tension of the spring is such as to temporarily hold the sheath in place in the desired position of adjustment. it should also be explained that the sheath adjacent the portion 17 or" the spring is provided witli a cavity 18 to allow the spring to move 'outwardly while passing over the rounded or curved enlargements 12 yof the portion 6 of the pin.

It must be understood that l do notlimit the vinvention to the details of construction set Vforth, except so far as maybe necessary in view of' the priorart. Attention is called to the fact that the sheath 7 is made Vof suoli length that its Yiiared open extremity'may be made to engage the hat on the side where the sheath is applied, the considerable length, both of the -erable range Vof adjustment, this being re- -quired in order that thesame pin may be employedwith hatsv hai/'ingr crowns of varying size, and to hold: the pin securely in place.

"provided with a plurality of alternate circumferential enlargements and depressions, and a sheath having a longitudinal bore sub- Y stantially equal in length to the length of said portion, means on said sheath to engage in said depressions to retain the sheath in adjusted position on the pin, the inner end of said sheath thus being adapted to engage with the sides of hats of varying sizes when the head of the pin engages the opposite sides.

A safety hat pin having a relatively long portion of its shank adjacent the point provided with a plurality of alternate eircumferential enlargements and depressions,

and an adjustable sheath open at one end only and having a longitudinal bore substantially equal in length to the length of said portion, said open end being ilared, and means at said liared end to engage in said depressions to retain the sheath in adjusted position on the pin, the inner flared end of the sheath being adapted to engage the sides of hats of' Varying sizes when the head of the pin engagesv the opposite sides.

In testimony whereof I aliix my signature.
